Sewing machine foot pedal adaptation

Jewelry Discussion
1

Hello Orchidland,

I hate to throw anything away if it can be reused or repaired. My
Husquevarna/Viking sewing machine has a broken internal part that
will cost $350 to repair!! A new machine costs about $260, does more
and is warrentied. No point in repairing the machine - just throw it
away (grimacing here).

The foot pedal works just fine. Is it possible to reuse this part to
replace a faulty flexshaft foot pedal, or other electic motor that
is capable of variable speeds??

What say you all?

lights look pretty at night, even without snow.

You can buy a new FootPedal from Ameritool Redding CA for $30 +
handling works like a charm. I have it on my Foredom, and Ameritool
Flat Lap.

Judy in Kansas,

Yes, a sewing machine foot speed control should work fine for flex
shaft motor.

Hopefully someone who knows more than me about motors will also reply

  • I know some, but only so far. In general, yes, it can be used. The
    most certain thing to do is to also salvage the motor, and then they
    will be matched. The problems arise with matching impedance and stuff,
    which is where my knowlege falters. Also the wiring. That means that
    maybe it will work but the motor burns out in a week, and the like. In
    general, though, a mechanical variable speed is just a variable
    rheostat, and can work with all sorts of things. But it’s better to
    know for sure than to just wire it up and cross your fingers. I can
    say from experience that crossing them really, really tightly doesn’t
    help…

Judy…I am new at posting here but I thought I would throw in my 2
cents about the foot pedal. I have been using a sewing machine pedal
for my dremel rotary tool for several years. It works great, however
I have noticed that I don’t get as high of rpms when rumming the
dremel through the pedal (with dremel speed permanently set to high),
as I do without the pedal attached, running the dremel on high. Not
knowing much about motors, I will not propose why, but it is worth
thinking about.
